Using ESC technology to improve the durability of cemented carbide thread blades

Inkqubo ye-ESC (i-Edge kunye ne-Surface conditioning) yinkqubo yokuphucula (i-passivation) kunye ne-polish surface ye-cut cut edge. Ngenkqubo ye-ESC, amandla omgca wesixhobo angaphuculwa, imeko yoxinzelelo lwangaphezulu iphuculwe, ixabiso le-roughness ye-surface liyancitshiswa, kwaye isixhobo sihlala si-1 ~ 4 amaxesha. 

Ukugaya i-oyile yonyaka kunye nokuveliswa kokusetyenziswa kombhobho wensimbi ngaphezu kweetoni ze-800,000, ukuqhutyelwa kwepayipi yentsimbi yepetroleum kufuneka kusetyenziswe inani elikhulu leentsimbi ezinemisonto (ikhulu lamawaka amaqhekeza / ngonyaka), ngoko ke ukusetyenziswa kobuchwephesha be-ESC ukuphucula umgangatho kunye nokuqina kwee-breaded blades kuneenzuzo ezibalulekileyo kwezoqoqosho.

1. Iimpawu zemilo ye-1 i-thread blades Eli phepha luhlobo lwe-blade ye-comb yamazinyo amathathu esetyenziselwa intambo yangaphandle ye-oil casing, kunye ne-blade material yi-YT715 cemented carbide. Kumda wokusika wezinyo ngalinye leblade, iingongoma ezili-11 ze-A ~ q zikhethiwe, apho inqaku le-H limela incam yencakuba, i-A kunye ne-Q imela umda wengcambu, kwaye i-D kunye ne-L imele icala lomda. Ekukhuliseni okuphezulu, umgca we-blade (oko kukuthi i-junction yangaphambili kunye nobuso obungasemva) akuwona umgca olula, kodwa indawo enzima. 

Ubukhali bomphetho bubonakaliswa yiradius re. I-blade isetyenziswe ukwenza i-edge ebukhali yendalo, njengoko kuboniswe kuMzobo.

Ukuze kuphuculwe ukuthembeka kunye nokuzinza kwesixhobo sokusika, i-honing echanekileyo yomda ngeteknoloji ye-ESC inokunyusa amandla e-edge (ukwandisa i-re), ukunciphisa ixabiso le-roughness ye-surface (ra

2. Itekhnoloji ye-ESC kunye ne-Vibration honing indlela ye-ESC (i-Edge kunye nonyango lokuqina komhlaba) inkqubo ngokomgaqo inokwahlulwa ibe ngumatshini, ikhemikhali, i-electrochemical, i-abrasive, i-thermal processing, i-electromagnetic kunye nezinye iindlela zobugcisa, ezifana ne-brush machine honing method, i-vibration abrasive honing method, indlela yokuphucula ukuqhuma kwesanti, indlela yokuphucula i-particle-speed particle. 

Kweli phepha, i-vibration abrasive honing method isetyenziselwa ukuqinisa umda womda we-thread blade, obonakaliswe ngotyalo-mali oluncinci kunye neendleko eziphantsi, kwaye unokunciphisa ngokufanelekileyo okanye ukuphelisa uxinzelelo olushiyekileyo kwi-blade surface, ngaloo ndlela ukwandisa ukuqina kwe-blade. Umatshini we-vibration we-honing yendabuko uqulunqwe yindlela yokugubha (i-motor, i-cam, intwasahlobo, njl.) Nangona kunjalo, kunzima ukuqinisekisa i-radius efanayo yomgca wokusika, impazamo ye-radius ye-tooth top kunye nengcambu yezinyo yi-0.02 ~ 0.09mm, echaphazela umgangatho womatshini kunye nobomi obusebenzayo be-threaded blade. 

Kweli phepha, uhlobo olutsha lwendlela yokungcangcazela yomatshini isetyenziselwa ukubuyisela ikhamera yemveli kunye nemoto ngohlobo olutsha lwenjini yokungcangcazela, i-abrasive ngumxube we-Emery kunye ne-boron carbide, kunye nentshukumo ehambelanayo phakathi kweblade kunye ne-abrasive iphuculwe ngokusebenzisa isilungiso esitsha, ukuze umphezulu wezinyo kunye nomphetho wolawulo oluphantsi kwe-radius ye-0 kunye nokuphucula i-radius ye-0. blade ubomi obusebenzayo.
